Benefits of technology
The present invention provides a working machine with a cover member for protecting an equipment room and a selector valve. The cover member is designed to withstand impacts from rocks or other objects, while still allowing the selector valve to be easily operated. The machine also includes a latch member and a support bracket for holding the latch member and the selector valve in place. The technical effect of this invention is to provide a reliable and durable working machine with improved safety features.
Problems solved by technology
The small radius of the small turning type restricts an equipment installation space.
On the other hand, giving a large distance between the selector valve and the guard cover involves a difficulty of the manual operation of the selector valve from outside of the guard cover.
However, the thus located selector valve 116 cannot be easily operated from outside.

A working machine comprising a frame, a working implement supported at a front end of the frame, a cover member, a latch member, a selector valve and a support bracket. The cover member has a cover-member body covering a side equipment room and having an opening, a lid member to open and close the opening, a lockable member attached to an inner side of the cover-member body near the opening, and a hinge portion interconnecting the frame and a rear end of the cover-member body and supporting the cover-member body. The latch member is disposed near the opening and inside the side equipment room to hold the cover member closed in cooperation with the lockable member. The support bracket extends from the side equipment room toward the opening and supports the latch member and the selector valve at the side of the frame. The support bracket has a selector valve-retaining portion supporting the selector valve and a latch member-retaining portion retaining the latch member at a position closer to the opening and higher than the selector valve.
Description
BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a working machine, such as a hydraulic shovel (excavator), having an equipment room and a cover member for covering the equipment room.[0003]2. Description of the Background Art[0004]Heretofore, as a construction machine having an equipment room, there has been known one type described in JP 2005-23727A. This working machine comprises a relatively large guard cover for covering hydraulic equipment. The guard cover is formed with a small window and provided with a small-window cover for selectively opening and closing the small window. The small-window cover is adapted to be strictly lockable by a keylock.[0005]The working machine further comprises a locking mechanism adapted to lock the guard cover in a closed state. The locking mechanism is disposed inward of the small window. This makes it necessary to open the small window and then release a lock function of the locking mechanism, for...
